Abstract: An electronic conditioning device delivers electric shocks correlated with sounds or driven by a signal associated with a sound sequence. The sound sequence can be a few seconds of a recorded human voice, a siren, a single tone, and so forth. A sound generator emits the sound sequence audibly. A power supply is electrically connected to the various components and provides energy to a shock inducer or electrodes embedded in the skin of a target. The device administers voltage spikes and sounds in a coordinated fashion. The conditioning encourages the target to associate certain sounds with the electric shock. Power may be supplied by a battery, a piezoelectric flexible film or movable magnet that converts kinetic motion into electric energy. Preferably, the device is applied to a target by loading the device into a shotgun shell and firing the loaded shell at the target from a rifle, pistol or shotgun.

Abstract: Vibration of a pager is sensed by a piezoelectric crystal. A buffered output of the crystal is connected through a low pass filter to an input of a retriggerable monostable multivibrator having a period of approximately twenty milliseconds. In response to the twenty millisecond multivibrator being retriggered to provide a recognition pulse having a duration of approximately three seconds, a latch is set. An output of the latch drives an LED circuit that provides a visual indication of a page. In response to the latch being set, an astable multivibrator provides alarm pulses having a duration of approximately eight seconds with a thirty second interval therebetween. The output of the latch and the output of the astable multivibrator drive an audio alarm circuit through a selector switch. When the switch is thrown in one direction, the setting of the latch causes the alarm circuit to provide a continuous audible sound.

Abstract: An apparatus used in search and rescue operations that combines the features of a dragstick with the features of a radio antenna. The apparatus is comprised of an aluminum rod split into two, adjustably connected sections. At one end of the rod is a metal spike, The metal spike is used to make identifying marks in the ground thereby allowing the searcher to retrace his steps. At the other end of the rod is an electrical connector which allows the rod to be coupled to a standard two-way radio via coaxial cable. When current flows through the rod it acts like a half wavelength, omni-directional antenna. One of the two sections can be extended from or retracted into the other section, thereby varying the operating frequency of the rod when the rod operates as an antenna. An insulated grip allows the user to hold the rod while electrical current is flowing therethrough.
